Unfinished aqueduct of Maintenon

The unfinished aqueduct of Maintenon, with its 47 unfinished arches, stands as a monumental vestige of a hydraulic dream envisioned by Louis XIV. This structure was part of an ambitious project to divert the waters of the Eure river toward Versailles, the royal residence of the French king.

Hydraulic project details

The project aimed to channel water via a canal exceeding 80 kilometers, with a three-level aqueduct designed by military engineer Vauban. This aqueduct was not intended for navigation but solely to transport water to the royal domain, highlighting the importance of water supply in the royal estate.

Construction and workforce

Between 1685 and 1688, approximately 30,000 men, including 20,000 soldiers, were mobilized for the project. The workforce faced harsh conditions, with workers exposed to malaria and other diseases, leading to an estimated death toll of nearly 10,000.

Project halt and repurposing

Only the first line of 47 arches was completed before the War of the League of Augsburg mobilized 20,000 soldiers elsewhere, halting the project. The aqueduct's construction site was later repurposed as an open-air stone quarry, with materials used for other buildings.

Historical recognition

The structure was classified as a historical monument in 1875, and its two characteristic arches were inscribed in 1934. Today, the 47 arches of Maintenon continue to attract visitors, serving as a reminder of the ambitious yet ultimately unrealized vision of Louis XIV.
